<p>PROBLEM TO BE SOLVED: To precisely restrain meandering of a belt even in any specification without impairing the service life of the belt. SOLUTION: Among a driving roller 11 round which a transfer belt 10 is wound, a tensile force applying roller 12 and two driven rollers 13, three rollers 12, 13 and 13 except the driving roller 11 are supported so as to be tiltable in the shaft direction, and contact pressure of the transfer belt 10 to the rollers 12, 13 and 13 is deviated to the shaft directional one end side by its tilting, and meandering of the transfer belt 10 is corrected. Since plural rollers can tilt, meandering adjusting width becomes wide, and the service life of the belt is not impaired.</p> |
